Physics Question on Current electricity
If an ammeter is to be used in place of a voltmeter, then we must connect with the ammeter a:
A
low resistance in parallel
B
high resistance in parallel
C
high resistance in series
D
low resistance in series
Answer
high resistance in series
Explanation
Solution
A voltmeter is a high resistance device and is always connected in parallel with the circuit. While an ammeter is a low resistance device and is always connected in series with the circuit. So, to use voltmeter in place of ammeter a high resistance must be connected in series with the circuit.
